Specification of Letters Patent.

Application filed April 13, 1908. Serial No. 426,740.

' siding in the city of St. Louis and State of Missouri, have inventedcertain new and useful Improvements in a Combined Base-Ring and Bracketfor Signal- Lamps, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawing, formingpart of this specification.

My invention relates to a base ring and bracket for signal lamps used inrailway service and it has for its object the construction of a deviceof this character, whichis simple in nature and affords a. high degreeof protection to the lower end of a signal lamp to prevent injury to theshell.

Figure I is a view partly in elevation and partly in vertical section ofa signal lamp having my ring and bracket applied thereto. Fig. 11 is across section taken on irregular line IIII, Fig. I. Fig. III is avertical cross section taken online III'III, Fig. II.

In the accompanying drawings: 1 designates the shell of a signal lamp,and 2 is the bottom within said shell that is located above the loweredge of the shell, as usual, thereby leaving the downwardly projectingshell extension 3 which is the part to which my base ring is applied forprotection of the lamp shell. I

4 designates a stiffener band that surrounds the shell extension 3 andis connected thereto by rivets 5 or other suitable means to increase therigidity of the lower end of the shell. a

6 designates a base ring that is provided with a bracket arm 7. Thisbase ring has a thickened lower portion which is located beneath thebottom edges of the shell extension 3 and the stiffener band 1, and atthe upper end of which is a shoulder 8 upon which the lower edges ofsaid members rest. The base ring also has an upper annular neck member 9that extends upwardly from the shoulder 8 of its thickened lower portionand fits loosely within the shell extension 3, so as to be susceptibleof turning therein, or in other Words, to provide for the lamp being'sion, substantially as turned upon the base ring for desired adjustment. The base ring is provided with a cross bar 10 by which the ringis rotatably held to the lamp shell, the connection of said cross bar tothe shell being furnished by a pivot bolt 11 that extends through thecenter of the shell bottom 2 and the cross bar, as seen in Figs. II andIII.

The base ring 6 fitted to the lamp shell as described, affords a veryhigh degree of protection for the bottom of the lamp shell, inasmuch asthe thickened lower portion of the ring is located immediately beneaththe bottom extension of the shell and the stiffener band 4, andtherefore furnishes a direct end bearing for said parts.

In order that the lamp may be held in any position to which it isadjusted upon the base ring, I provide a spring latch 12 that issecuredat one end to the stiffener band 4 and the free end of which isconfined within a keeper 13 carried by said band. The latch is providedwith a catch pin 14 that passes through perforations in the stiffenerband and the shell extension 3, andis adapted to enter into any one of aplurality of perforations 9 in the neck 9 of the base ring, when thelamp is turned upon the base ring.

I claim:

1. The combination with a lamp of the character described having a shellprovided with a bottom and an extension projecting downwardly from saidbottom, of a base ring having a thickened lower portion located beneathsaid extension, and an upper annular neck member fitted within saidshell extension, substantially as set forth.

2. The combination with a lamp of the character described having abottom and an extension projecting downwardly from said bottom, of astiffener band secured to said extension, and a base ring having athickened lower portion located beneath said extension and stiffenerband, and an upper annular neck member fitted within said extensetforth.
